Hi, I followed this http://www.howtoforge.com/using-roundcube-webmail-with-ispconfig-3-on-debian-wheezy-apache2, to install roundcube on debian 7, ispconfig 18.104.22.168. After I finished with installation, source code of index.php was shown on http://site/webmail. To test php, I create file /var/lib/roundcube/test.php Code: <?php phpinfo(); ?> and got empty page when I open it http://site/webmail/test.php. Php is working Ok on main site. I guess I have misconfigured system. Any suggestion what to check next?
